Cannot resolve symbol 'i' in Day array

I've followed exactly what Ben has typed out but my code cant resolve symbol 'i'

 private Day[] getDailyForecast(String jsonData) throws JSONException {
        JSONObject forecast = new JSONObject(jsonData);
        String timezone = forecast.getString("timezone");
        JSONObject daily = forecast.getJSONObject("daily");
        JSONArray data = daily.getJSONArray("data");

        Day[] days = new Day[data.length()];

        for (int i = 0; i < data.length(); i++); {
            JSONObject jsonDay = data.getJSONObject(i); //<--- this is where I get the error 'Cannot resolve symbol'
            Day day = new Day();

            day.setSummary(jsonDay.getString("summary"));
            day.setIcon(jsonDay.getString("summary"));
            day.setTemperatureMax(jsonDay.getDouble("temperatureMax"));
            day.setTime(jsonDay.getLong("time"));
            day.setTimezone(timezone);

            days[i] = day;
        }

        return days;
    }

Thank you very much.

You have a semicolon after the closing paren of the for loop. This ends the for statement and makes the declared i variable no longer valid.

 for (int i = 0; i < data.length(); i++);  // <-- Remove that semicolon
